Entrapments of humans, exposures to gas, and inundations of water occur in mines since complete, accurate maps do not exist. Submergence, roof
fall, rotted timbers and water seals prevent human access for mapping old mines, and they motivate the use of robots. Robots offer unique
capabilities with safety and cost advantages for mapping abandoned mines, but the technical challenges are profound.

The presentation will profile the technologies and accomplishments toward robotic mine mapping. Content will describe what mine robots are,
how they build maps, how they know where they are and where they are going. Robot mapping will be compared to human-surveyed mapping to
illustrate the distinctions of the new technology. The presentation will showcase new robot developments and the robotic mapping of a mine to convey the power of the technology in action. We will share the
experience of exploration and mapping to graphically understand the principles and capabilities offered by the technology.
